Surface Coatings and Functionalization Strategies for Corrosion Mitigation

Abstract

Nanomaterials have a wide variety of applications in industries due to their unique multifunctional properties they provide to surface functionalization and modified coatings. Various industrial applications require high corrosion and oxidation resistance, improved adhesion, excellent superhydrophobic and antifouling properties for longer life of structural components exposed to harsh environments. Energy, food-safety and healthcare, pollution monitoring, preservation of cultural monuments, are all depend upon the ability to engineer the surfaces. The application of various nanomaterials in drug delivery and treatment of human diseases like cancer is of increasing interest. The cytotoxicity of these nanomaterials in cellular growth and efficiency limits their applications in clinical practice. Several physical and chemical properties of these nanomaterials such as charge, composition, and shape play an important role in the surface modification and improving the functional properties of these nanostructured materials and coatings. Nanomodified coatings and surfaces minimize corrosion rate, impart surface protection, improve biocompatibility and service life of the components through the functionalization of the surfaces. Several key nanomaterials and their coatings have been employed for imaging, sensing, and delivery applications. The impact of coatings and interfaces in technology is growing at an unprecedented pace. Here, in this chapter, the authors highlight different types of coatings and methods for corrosion protection methodologies used in various applications. This chapter details various innovative methods for surface functionalization and modification for preventing the corrosion without any change in the base metal substrate. The authors aim to describe various methods and approaches used for the surface modification and functionalization methods using nanostructured materials, nanoparticles, polymers and coating technologies followed by future scope of these surface modification technologies in industry and academia.
